LEN
Counts the characters in a text.
What it does
LEN returns how many characters a text has. Spaces, punctuation and digits all count. It is useful for checking codes that must have a fixed length, and as a building block with LEFT, RIGHT and MID.
Syntax
=LEN(text)Arguments in square brackets are optional, and … means you can add more of the same. In this Excel language, arguments are separated by ;
Arguments
- text
- The text to measure, usually a cell.
Example
Stock codes should be 9 characters long. Is this one?
| A | B | |
|---|---|---|
| 1 | Code | Length |
| 2 | SKU-40518 | 9 |
The formula in B2:
=LEN(A2)Result: 9
SKU-40518 has three letters, a hyphen and five digits: 3 + 1 + 5 = 9.
Common mistakes
- Forgetting that spaces count, including ones you can't see at the end of a cell. Clean them with
TRIMfirst. - Expecting a number's formatting to count.
LENmeasures the stored value, so 0.5 shown as 50% still has 3 characters.
